The dual side exhaust on the Coupe is loud. When it went in for it's first MOT there was a lot of discussion around the equipment going "faulty" at the wrong moment. When I start the car in the garage it echos all down the road. I switch it off when it is resting on the drive or SWMBO gives me the little look of shame. I have lined the lower half of the garage with absorbent board to reduce it now. I try and keep my arrival/departure times to more reasonable hours.
When on full power to overtake in the narrow local roads it is very loud. I try and plan the overtake so the power is used prior to coming alongside the car being passed so I don't blow their doors off.
I do also make the same comments where I hear a Ferrari go screaming up the high street !
